Cannabis fiber, absorbent cellulosic structures containing cannabis fiber and methods of making the same

a technology cannabis fiber, which is applied in the direction of non-fibrous pulp addition, paper-making, coatings, etc., can solve the problems of inability to economically viable hemp, inability to grow and use cannabis solely, and inability to meet the needs of a large number of people, so as to achieve low base weight, reduce the manufacturing cost of absorbent cellulosic structure, and high pectin concentration

Benefits of technology

[0009]Another object of the present invention is to provide a use for cannabis hurd fibers when only bast fibers are used for the manufacture of paper products.
[0010]According to an exemplary embodiment of the invention, Northern Bleached Softwood Kraft pulp is replaced wholly or in part with cannabis bast fiber and eucalyptus fiber to lower the manufacturing cost of absorbent cellulosic structures. In accordance with the invention, the cannabis bast fibers are prepared, pulped, and bleached to allow for the fiber to be incorporated into absorbent cellulosic structures on a wet-laid asset while retaining all or a substantial amount of the pectin with

Problems solved by technology

Unfortunately; during the period of prohibition; cultivation knowledge, processing equipment, and expertise had been optimized for other natural fibers, such as cotton, and synthetic polymer fibers, resulting in hemp not being economically viable.
Today, the growth and use of cannabis is extremely small and relegated to production of the seed for sale to the food industry.

Embodiment Construction

[0025]The headings used herein are for organizational purposes only and are not meant to be used to limit the scope of the description or the claims. As used throughout this application, the words “may” and “can” are used in a permissive sense (i.e., meaning having the potential to), rather than the mandatory sense (i.e., meaning must). Similarly, the words “include,”“including,” and “includes” mean including but not limited to. To facilitate understanding, like reference numerals have been used, where possible, to designate like elements common to the figures.

[0026]The present invention is directed to the use of cannabis fibers in the base sheet of absorbent products, such as tissue or towel products. Such tissue and towel products may be formed using the systems and methods described in U.S. application Ser. No. 13 / 837,685 (issued as U.S. Pat. No. 8,968,517); Ser. No. 14 / 534,631; and Ser. No. 14 / 561,802, the contents of which are incorporated herein by reference in their entirety....

Abstract

A method to prepare, pulp, and bleach cannabis bast and hurd fibers to allow for the fiber to be incorporated into absorbent cellulosic structures on a wet-laid paper machine while keeping the pectin within the fibers. The wet laid paper machine can use the ATMOS, NTT, ETAD, TAD, or UCTAD method to produce the absorbent cellulosic structure. Absorbent cellulosic structures are produced with the cannabis bast and hurd fibers or with the bast fibers alone with the hurd fibers being combined with paper mill sludge or dust to form a fuel pellet.

Description

RELATED APPLICATION[0001]This application is a non-provisional based on U.S. Provisional Patent Application No. 62 / 078,737, filed Nov. 12, 2014, the contents of which are incorporated herein by reference in their entirety.FIELD OF THE INVENTION[0002]The present disclosure relates to absorbent cellulosic structures manufactured using cannabis fibers containing pectin.BACKGROUND[0003]Cannabis is a genus of flowering plants that includes three different species, Cannabis sativa, Cannabis indica, and Cannabis ruderalis. Cannabis has long been used for fiber (hemp), for seed and seed oils, and recently for medicinal purposes. In the mid-1930's, the growth of cannabis plants was outlawed in most countries due to its usage as a recreational psychoactive drug. In the 1970's, the ability to test and breed plants to contain low levels of the psychoactive drug, tetra-hydro-cannabinol (THC), became possible. Since this time, many countries have legalized the cultivation of cannabis plants that ...
